The intense research on small molecule inhibitors of Human immunodeficiency virus (HIV)-protease (PR) has produced a diverse class of chemical scaffolds which includes clinically available HIV PR inhibitors (PRI). Till now, these inhibitors are insignificant for targeting proteolytic activity and few drug molecules on alterations can enhance the inhibition(More)
Tuberculosis is a highly communicable and chronic respiratory disease caused by pathogenic bacterium Mycobacterium tuberculosis. The drug - resistant species of Mycobacterium tuberculosis are tough to cure due to its resistant activity toward potential drugs. Available inhibitors of tuberculosis include few antimicrobial fluoroquinolone agents like(More)
Calpain, a member of the group of cysteine protease enzymes, has been recognized as a promising drug target for several diseases, including cataract. In the present study, an attempt was made to identify potential inhibitors of calpain by employing a pharmacophore-based virtual screening and docking approach. A knowledge-based 3D pharmacophore model was(More)
Cyclin-dependent kinases (CDKs) are core components of the cell cycle machinery that govern the transition between phases during cell cycle progression. Abnormalities in CDKs activity and regulation are common features of cancer, making CDK family members attractive targets for the development of anticancer drugs. Their inhibitors have entered in clinical(More)
HIV-1 integrase (IN) is an important drug target over the years with diverse therapeutic potential with the objective of designing new chemical entities with enhanced inhibitory potencies against HIV-1 IN. We performed molecular docking, quantum polarized ligand docking (QPLD), ADME screening, and PASS biological activity prediction studies on Raltegravir,(More)
Quinolone resistance-determining region is known to be the druggability site of the target protein that undergoes frequent mutation and thus renders quinolone resistance. In the present study, ligands were tested for their inhibitory activity against DNA gyrase of Streptococcus pyogenes involved in DNA replication. In silico mutational analysis on modelled(More)
DNA binding ligands (DBL) were reported to bind the minor groove of bacterial DNA. In the present study, DBL were analyzed and screened for their Staphylococcus inhibitory activity by inhibiting the Staphylococcal DNA replication. The orientation and the ligand-receptor interactions of DBL within the DNA-binding pocket were investigated applying a(More)
The development of SrtA inhibitors targeting the biothreat organism namely Bacillus anthracis was achieved by the combined approach of pharmacophore modeling, binding interactions, electron transferring capacity, ADME, and Molecular dynamics studies. In this study, experimentally reported Ba-SrtA inhibitors (pyridazinone and pyrazolethione derivatives) were(More)
HIV-1 integrase (IN) is a retroviral enzyme that catalyses integration of the reverse-transcribed viral DNA into the host genome, which is necessary for efficient viral replication. In this study, we have performed an in silico virtual screening for the identification of potential HIV-1 IN strand transfer (ST) inhibitors. Pharmacophore modelling and(More)
Enterococcus faecalis is a pathogenic Gram-positive bacterium, which mainly infects humans through urinary tract infections. SrtA is an essential enzyme for survival of E. faecalis, and inhibition of this particular enzyme will reduce the virulence of biofilm formation. It is proved to be associated with the microbial surface protein embedded signal(More)
